Anisotropic Pre-stack Time Migration (PSTM)

We use noise attenuated, 5D regularized gathers with extended maximum offset for further AVO analysis as input to our PSTM.

Within our interactive velocity analysis tools we include an option to correct the far offsets in the presence of anisotropy. The correction values, which may vary in time and space, are used in our Kirchhoff pre-stack migration.
